Installation

Dont't install NFSEN on the server with DPI platform: report generation is CPU resource intensive, so it may result in worsening of DPI platform performance

Install the exact time service

yum install ntp -y
ntpdate pool.ntp.org
service ntpd start
chkconfig ntpd on

Add the vasexperts repository

rpm --import http://vasexperts.ru/centos/RPM-GPG-KEY-vasexperts.ru
rpm -Uvh http://vasexperts.ru/centos/6/x86_64/vasexperts-repo-2-1.noarch.rpm

Install NFSEN (Apache WEB server is installed along with NFSEN):
```
yum install nfsen
```
Check that the service can be started:
```
service httpd start
service nfsen start
```
Configure the service to start automatically on power on:
```
chkconfig httpd on
chkconfig nfsen on
```

Open firewall ports to access Apache and to get netflow:

vi /etc/sysconfig/iptables
-A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT
-A INPUT -m state --state NEW -m udp -p udp --dport 9997 -j ACCEPT
-A INPUT -m state --state NEW -m udp -p udp --dport 9998 -j ACCEPT

Switch off selinux ¹⁾

setenforce 0
vi /etc/selinux/config
SELINUX=disabled

Open the page http://hostname/nfsen/nfsen.php in your browser. Here hostname - is the name or address of nfsen server. Check that everything works fine.
